Corvex And Related Urge CommonWealth Shareholders To Act Now To Remove Board Of Trustees

NEW YORK,
March 14, 2014 /PRNewswire/ -- Corvex Management LP and Related Fund Management, LLC, whose separately managed investment funds collectively own approximately 9.6% of the outstanding shares of CommonWealth REIT (NYSE:CWH) today reminded CommonWealth shareholders that the deadline to support the consent solicitation and remove the entire Board of Trustees is approaching. There is no internet voting, so shareholders are urged to sign, date and return their GOLD consent card in the pre-paid envelope today.

In addition, Corvex and Related released a new presentation that dispels CommonWealth's recent series of desperate, disingenuous and diversionary tactics. It should be noted that CommonWealth's behavior comes following the recommendations of both Institutional Shareholder Services (ISS) and Glass Lewis & Co. to remove all of CommonWealth Trustees.

If you have any questions or need assistance voting your shares, please call today
D.F. King & Co., Inc., our proxy solicitor, at (800) 714-3313. Also visit us at
